REGULATOR FOB BOYVING." OB YARN.

To all-whom it may concern:

Be it known that I, DANIEL DERMoNn, of

' the city r and county of Philadelphia and State of Pennsylvania, have invented a new and Improved Relgator for Regulating the Size of Yarns or vings; and I do hereby declare that the following is a full; clear, and exact description of the same, reference being had to the accompanying drawings,

suitable bearings on the framing of the jenn or other machine, some distance below the rawiri rollers, said shaft having firmly secured to 1t the pulley 1 3, whose duty is to drive the heckle-chain by a belt running from the said pulley to a pulley on one of the shafts whi carries the heckle chain. A

C, is a cylindrical metal box fitted con centrically to the shaft A, in such a manner as 'to be capable of turning freely on the said shaft, said box having a series of ratchet teeth a, a, extending all around its outer periphery, and containing a partition b, arranged perpendicularly to its axis, which partition may be either a close one or a skeleton, as its purpose is to contain the bearings for some gearing which is inclosed within the box. Y

D, E, isa vbent lever workin on'a fixed fulcrum c, and having' attach D, a catchd, which serves asv a Istop to the ratchet a, a, and having lits other arm E connected to a spring e, tends to draw down l. the catch into .gear with the ratchet. Ther arm D, of the lever is intended to be con-l nected by a red f, with the weighted lever commonly employed to apply) the requisite pressure to the upper vdrawin roller. The

drawing rollers-and heckle c ain are sup-v toibefarranged in the usual manner. F, is a sleeve fitted tofrotate freely upon the s shaft A, said sleeve lbeing arranged partly within the box C, and partly outside ofit, but, capable of rotating independently to itsi armV within the box -a spur gear g, and to the part outsidethe box a pulley G. The gear g, is

geared through the agency ofv an intermedi ate gear l, (see Fig. 1) which is fitted to rotate freely upon a stud m, secured in the partition b, with a gear h', that is Asecured-on 'small shaft i, which rotates in a suitable bearing in the partition b, and which cai ries at its other end a spur r y", enga g with'a' gear c,that is secur tothe sha The box C, is constructed with tightly' fitted movable heads vn, n, which are secured' in their places by bolts o, o, passing througlh the box, and these headsserve Yto prevent. t e escape of oilfrom the gearing. `The oil `is to be supplied through a'hole inone of the of the box and having attached to the part heads, said hole to be providedwith a lug or stopper, and the oil finds its way m- .one compartment of the. box to the `other through the holes Ywhich'are made, in the partition b, for the passage of the boltso o.

The pulley G, recelves a driving belt either from a pulley onthe lower-'drawin rollerl which imparts motion to it in the dlrection of the arrowA shown on it in Fig. 1, and the revolution of this pulley is caused to 'give to the. pulleyB, which drives the heckle chain, a motion that is controlled by the operation als` of the catch d, upon'the ratchet a, in lsuch a manner that the movement of the heckle chain will be arrested assoonas the sliver resenting itself between the drawing rollers is larger than is required and will not bev again permitted till the sliver is drawn to the requisite size. This operation is effected .m the following manner. 'While the sliver enter-in vbetween the drawing rollers is noty Y above t e requisite size the catch d, 4is held down into the ratcheta, a, by the spring` and the revolution of thebox with the pulfv -ley'Gr",` being thereby prevented, the gear `gives vmotion through the gears l, and shaftfi, and'gear j, t0 the gear k, and'there gives rotary `motion to the shaft A, and

pul yB, but'the slightest. increase infthe size ofthe sliver causes. it to raise the `u per draw roller and with it the wei ted lever 't at gives it the requisite pressurel causing the saidlever to lift the rod F, andI the arm D, of the catch lever D, E, 'and raise i Y the 'catch d, out ofthe ratchet (z, 'when the r g, instead of giving motion to the gear on its stud 11n-,carries around` the box C, along with the pulleyl G,. and then the gear j,

of tbe'gear 7c, merely rollsA around the gear`c' Without giving motion to it, and the shaft A,y becomes stationary and`therefore the movement of the heckle chain ceases; and this continues until the -sliver isy drawn sufficiently when the upper drawing roller is permitted to descend and the catch d, to engage the ratchet again, and

arrest the revolution ofthe box C, when the gear la, and shaft A, are caused to revolve again as at rst described vand give motion to the heckle chain. In this Way the movement of the heckle chain is controlled so as to perfe'ctly control the size of the sliver.

The intermediate gear l, may be dispensed with andthe gear lz, made to engage directly with g, but in that ease the movement of the shaft A and pulley B, relatively to the pulley G, Would be the reverse of what it is when the arrangement shown in the draw' ing is used and a vcrossed belt would 'be required to drive the heckle chain instead of an openl one.

I am aware that a contrivance has been patented by Pearson and Gardner in which a brake and system of bevel gearing are o0n trolled by the upper feed roller 1n ysuchtmanner as to cause' it to control the movey ment of the heckle chain for th'e pu of regulating the size of the sliver an -there` and inclosed box C, with theratchet a, and v p'ositive stop' d, the whole arranged applied and operating substantially as andV for the.

purpose herein set forth.
